Subject: [PATCH] fix(linkify): strip trailing quotes from auto-linked URLs

The linkify parser trims trailing punctuation (., ), ;) from
auto-detected URLs but does not handle quote characters. When
combined with the typographer extension, a URL like:

    "https://example.org/"

produces a broken href with the closing quote encoded as %22,
because linkify includes it in the URL before typographer can
convert it to a smart quote.

Strip trailing double and single quotes from auto-linked URLs,
matching the existing behavior for other trailing punctuation.

Fixes #335
